FIRE DETECTION IN TuSim BY FibroLaser.

Road tunnels are important part of traffic infrastructure not only for shortening the paths in mountainous regions or in towns but also they increase economical effectiveness. Occurrence of traffic accidents in the tunnel is less common, but consequences can be more serious. The contribution shows the simulation of fire in a road tunnel through programmable logic controller (PLC) based simulator. Fire detection in the tunnel model is realized by FibroLaser. Influence of the pressure difference for various fire scenarios, types of vehicle on the air speed, etc. is counted by evaluation of the average temperature in the fire section. [ABSTRACT FROM AUTHOR]
